【 摘 要 】
This paper proposes an approach for the space-fractional diffusion equation in one dimension. Since fractional differential operators are non-local, two main difficulties arise after discretization and solving using Gaussian elimination: how to handle the memory requirement ofper iteration. Finally, some numerical results are shown to verify the accuracy and efficiency of the new method.
